Pearl Gourami Care Guide: Tank Size, Tankmates & Setup
The pearl gourami (Trichopodus leerii) is one of the most elegant centerpiece fish in the freshwater hobby. Its lacy, pearl-spotted body, the dark line running snout to tail, and the warm orange-red throat that males flush during display make it a living showpiece, and it does all of this with a calm, easygoing temperament. They are hardy labyrinth fish that breathe air from the surface, which makes them forgiving and a joy to keep. We regularly stock pearl gouramis here at Tropical Treasures, alongside our wider range of labyrinth fish. Stock rotates, so if you do not see them listed just message us and we will let you know what is swimming.
Meet the Pearl Gourami
Pearl gouramis are native to the slow, vegetation-choked waters of the Malay Peninsula, Sumatra, and Borneo. They reach about 4–5 inches and can live 4–5 years or more with good care. As labyrinth fish, they gulp air from the surface in addition to using their gills, so they thrive even in gently filtered, oxygen-poor planted tanks. If you love centerpiece gouramis, you may also enjoy our dwarf gourami and the tiny, vocal sparkling gourami.
Tank Size and Setup
Give a pearl gourami at least a 30-gallon tank, and larger if you plan to keep a small group. They appreciate a heavily planted layout with plenty of cover, a darker substrate to show off their coloration, and calm water with minimal current. Floating plants such as Amazon frogbit are a particular favorite, since they diffuse the light, provide security, and give males a place to build their bubble nests. Round out the aquascape with live plants for a natural, settled feel.
Water Parameters and Temperature
Pearl gouramis are adaptable but do best in soft to moderately hard water. Aim for a temperature of 77–82°F, a pH of 6.0–7.5, and stable, well-maintained conditions. Because they breathe surface air, keep the lid in place to trap a layer of warm, humid air above the water—a sudden draft on the surface can chill that labyrinth organ. Otherwise, routine weekly water changes and slow acclimation of new arrivals are all they ask.
Feeding Your Pearl Gourami
These are unfussy omnivores that will happily take a quality flake or a community pellet as a staple, supplemented with frozen or live foods like bloodworms, brine shrimp, and daphnia. They are also useful in planted tanks because they nibble at small pest organisms, including hydra. Browse our full range of freshwater fish food to keep yours in peak color and condition.
Tankmates and Temperament
Pearl gouramis are among the most peaceful of the larger gouramis, which makes them outstanding community centerpieces. Pair them with calm, similarly sized fish rather than fin-nippers. Excellent companions include harlequin rasboras, rummynose tetras, and peaceful bottom dwellers like pygmy corydoras and other corydoras catfish. Keep just one male per tank unless you have a lot of space, since males can spar over territory. For more ideas, browse our community fish and beginner-friendly fish collections.
Is the Pearl Gourami Right for You?
If you want a graceful, peaceful centerpiece that brings movement and color to a planted community tank without the aggression of some larger gouramis, the pearl gourami is an outstanding choice. They are hardy enough for confident beginners yet beautiful enough to anchor an aquascaper's show tank.

Frequently Asked Questions
How big do pearl gouramis get? Most reach about 4–5 inches as adults, with males growing a touch larger and developing more pointed dorsal and anal fins plus the bright orange-red throat.
Can I keep more than one pearl gourami together? Yes, but keep just one male per tank unless the aquarium is large and well planted. A male with two or three females, or a small group in a roomy planted tank, works beautifully.
Are pearl gouramis good for beginners? They are. As hardy labyrinth fish they tolerate a range of conditions and are very peaceful, so as long as you provide a planted tank, stable warm water, and a covered surface, they are an easy and rewarding centerpiece.
